standard day differs from that previously used, the data for the 
“corrected” heat production differ, of course, from those which have 
been published. In order to make it possible to follow the recom- 
putation of the net-energy values the complete data are presented in 
Table II. The gains of energy given in the last column of the table 
are computed by subtracting the corrected heat production from 
the metabolizable energy.
